Procedure

To a mixed solution of N-[(3aS,4R,6R,6aR)-6-({[tert-butyl(dimethyl)silyl]oxy}-methyl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl]-6-chloropyrimidin-4-amine (405 mg, 0.98 mmol) in THF (10.0 mL) and DMF (2.50 mL) was added sodium hydride (47.0 mg, 1.17 mmol) under an atmosphere of Argon, and the mixture was stirred for 15 minutes. Methyl iodide (0.08 mL, 1.27 mmol) was added to the mixture, and the resulting mixture was stirred for 1 h. After quenching by addition of brine (20.0 mL), the mixture was extracted with ethyl acetate (3×40.0 mL). The organic layers were combined, dried over MgSO4, filtered, and evaporated under vacuum. The residue was purified via silica gel column chromatography eluting with a gradient of 5 to 15% ethyl acetate in DCM to afford the title compound (381 mg, 91%) as a colorless oil. LC/MS: Rt=2.55 min, ES+ 428.3 (AA standard).
